Abstract

Stretchable multilayer films in which at least one outer layer (A) comprises a linear low density polyethylene (LLDPE), at least one intermediate layer (B) comprises a polyolefin composition containing LLDPE and a propylene polymer having an insolubility in xylene higher than 70%, and at least another layer (C) comprises a very low density polyethylene (VLDPE). bSaid films show an excellent balance between mechanical properties, represented as tear resistance and strength at break, and optical properties represented as gloss and haze.
